Be 1t known that I, JAMES'L. BRENNAN,

a citizen of the fUnitedfStateS; residing at useful improvements in surgical appliances and relates particularlyto an improved construction of a" truss adapted for"the treat mentof rupture orl1ern1a, and the improve ment residesin the construction, combination and operative arrangementof parts set forth in the following specification vandf fall; iug within the scope of the appended claims 1 cilitate in the application of the threaded iie nheror screwfi. The screw is adapted to enter one of a plurality of spaced thread: ed orifices 6 respectively provided centrally In the drawings Figure 1 is a viewof thejclevice as applied to a single rupture, Flg. 2 s a s m lar v1ew 11llustrat 1ng the device applied to a double .rupture;

.The member (or element; .11 maybe cut to meral 3, thesaid reinforcing member being Patented Jaime, 191%; 1 Application filedhpril 17., 1917. Serial 2910, 162,722; 1

preferably constrncted of leather, and in Figf2 tivoof such reinforcingmembers are illustrated. The reinforcingin Fig. 1 is provided wlth a central. opening remforced by an eyelet 4;, while the reinforcements in F 1g; are provlded Wlth three openings, one being centrally arranged and the others being disposed approximately.equi-distantly UL from the said central opening, all of the openings heing protected by suitable eye- Ilets. lhrough these eyelets are adapted to be passedthe threaded shanks of headed "members ,5, the heads of 'the saiol members [being kerfed wherehyto receive asuitable instrument, suchias a-screw driver,;to fain'the rear of the back or plate}? for the flat'member having an oval periphery, and

the said periphery adjacent the inner f ace of each of the 'plates'is formed .withna con-- tinuous groove or channel 8 while each of the said plates at oneof the endsthereof and outward, of the groove 8 1s formed wlth a transverse slot 9 T he mner face of each erabl throu h the medium of a sin 'le sible: and absorbent material .11, and around this element; 11 iswound the strip 12 that an elliptictal shape, and the strip comprising nature of awick, the innerendof the same being'narrower than the outer end, the said inner and-reduced"; end being arranged in contacting relation With the element 11, the

strip comprising the cushion member being wound around the said member 11 and around itself "to an elliptical formation; corresponding to the 'shapeof the backplate i7. Thisarrangement, it will be noted, pro

:vides for'the inner dished or hollow shape The threadllO preferably has. its end 'passedthrough apertures in the plate 7 the plate; and the thread 10 cell trally passes through the open woven washable cover 13 whereby to secure the said;

, brought over the face as well as the sides ofthe cushion and to be arranged over the groove or channel 8 of the plate 7. A cord or string 14 is brought over the edge of the cover 13 forcing the said edge to within the groove 8, and by tying or otherwise connecting the end of the cord or string the cover is effectively retained over the cushion and upon the back plate 7.

The numerals 15 designate the understraps for the device, one of the ends of each of said understraps being arranged within the slot 9 of the plate? and removably connected thereto, as at 16, the opposite end of each of said straps being received,

by a buckle member 17 arranged upon and protected by a depending portion 18 of a yoke 19. Each of the yokes' 19 is arranged upon' the belt 1 and can be adjusted to any desired position with respect to the said belt.

The swivel connection of the pad with the reinforcement of the belt permits of the said belt being brought to proper position on the person of the user wearing the said pad to work upon the pivot or swivel with the movement of the body and the plurality of eyelets in the said reinforcements allow adjustment for distances, while the washer 20 upon the outer face of the plate as illustrated in Fig. l of the drawings permits of the increasing of the pressure of the pad upon theperson of the user.

The hollow concaved or saucer shape of the shell with the open, woven, washable cover allows for'the free circulation of air next to the skin, and such circulation will prevent irritation to the skin. The moisture absorbing cushion is of a very light and soft material, and wound in the manner described not only provides for the central concavity in the face of the shield but the materlal of the same'permits of it being washed by simply dipping the same in water and squeezing the cushion in the manner in which water is squeezed from asponge. The construction of the back with the plurality of threaded orifices to receive the pivot'or swivel member permits of a vertical adjustment of the pad and the advantage of removably connecting the edge of the cover to the back will, it is thought, be apparent. The pad when applied to the user will automatically adjust itself and when the same is properly embedded in place. the understraps 15 may be removed,

Gopies of this patent may be obtained for The central portion of so that the patient will be relieved from any annoyance which the same may occasion.

From the foregoing the simplicity and advantages of the construction will, it is thought, be apparent to those skilledint-he art to which such invention appertains without further detailed description. it being understood, of course, that if desired the compresslble member orcore 11 may be dispensed with and that the cover 13 may be attached to the inner and reduced endfof the strip comprising the cushion member 12.

Having thus described the invention, what Icla'im is: ,7 r

1. In a rupture appliance, a pad including anoval back having a peripheral roove, a compressible core centrally securedto the back, an absorbent cushion comprising a strip which gradually decreases. in width from its inner to its outer endand wound around the core, an open'woven cover se cured to'the coreand designed to have 1ts edges lap the edges of the back, and a tying element for the cushion whereby to force the edge ofthe same to within the groove of the back to secure the edg of the said cushion to the back.

2. A rupture appliance including a nonyieldable back which" is oval in plan, said back having a peripheral groove and hav ing one of its edges provided with a transverse slot, a cushion member comprising strip of absorbent material gradually decreasing in w1dth fromitsinner to its outer end and being wound upon itself'and cen trally connected with the back, a belt, means for adjustably and pivotally connectingfthe back to the belt, a back strap adjustably secured to the belt and having one of its ends received in the slot of the back, removablemeans for retaining the said end in the said slot, an open woven cover centrally connected to the cushion, said cover designed to overliethe end of. unseat,

cushion and the periphery oftheback, and

means comprising a flexible element wound around the edgeofthe' cushion to compress the same in the grooveof the back.

3. In a rupture appliance, -a pad includingan oval back-having a peripheral groove, an absorbent cushion upon the back comprising awoven stripwhich is wound upon itself whereby to conform to the'peripheral formation of the back, an open woven cover arranged'over the cushion and over the edge of the back, a tying element designed to engagewith the said cover to force the same in the peripheral groove of the back and sustain the same upon the back and in contacting relation with-the cushion.

In testimony whereof I affix mvsignature.
